What do I put down on schedule C for a 1099?

Put down where?   Did you get a 1099NEC or did you issue a 1099NEC for someone you paid?

How to enter income from Self Employment

Actually I would just enter your total income as Other self employment income or as Cash or General income.  You don't need to get a 1099NEC or 1099Misc or 1099K.  Even if you did you can enter all your income as Cash.  Only the total goes to schedule C.

If you have a Schedule C, and your received a Form 1099-NEC related to your business, enter it in the Business section of Home & Business or other TurboTax product for self-employed, rather than in the Other Common Income section of Personal Income.
